The Long, Extraordinary Career of Steve Jobs

Rock and Roll
In 2001 Jobs initiated another paradigm shift with the introduction of the iPod. Though it did little to advance the functionality of earlier portable music players, it featured superior usability and a sleek design. What's more, its rollout was accompanied by the debut of iTunes, a Web-based music store that permanently reshaped the parameters of the music industry. U2 band members Bono and the Edge, above, joined Jobs at an iPod promo event in 2004.
